Application filed August 4, 1913. Serial No. 782,877.

To all whom it may concern:

Be it known that I, WILLIAM OoRwIN RIoKETTs, of the city of Dayton, county of Montgomery, State of Ohio, United States of America, construction engineer, having invented certain new and useful Improvements in Reinforced-Concrete and Masonry Construction, do hereby declare that the following is a clear, full, and exact description of the said invention, reference being had to the accompanying drawings, in which Figure 1, an isometric view of the 2 unit invented and is used throughout this construction. Fig. 2, an isometric view of the method of bonding this unit in the wall. Fig. 3, an isometric view of an unfinished wall showing vertical and horizontal reinforcements in place. Fig. 4:, a plan view of a wall of triple thickness, forheavy construction having a reinforced concrete center and hollow outside courses. Fig. 5, is a vertical section of a triple thickness wall with reinforced concrete center in combination with a concrete floor. Fig. 6, an isometric view of a fragmentary portion of a combined reinforced concrete hollow tile floor and reinforced concrete columns in a hollow wall, constructed entirely of Z tile. Fig. 7 a vertical cross section at the intersection of a continuous floor and a supporting wall. Fig. 8, a section of the floor in Fig. 6 with a cement top. Fig. 9, a section of the floor in Fig. 6 with a wood floor top.

My invention relates to buildings or structures of masonry in combination with reinforced concrete, and the object of my several inventions is to produce a reinforced concrete structure within a masonry structure, without the use of forms, and with a minimum of material and labor.

Similar letters refer to similar parts throughout the several views.

In the practical application of my invention, I vary the amount of reinforcement steel, and the size and number of reinforcements in the diiferent members through the structure as strength demands.

The unit used throughout my several in ventions and upon which the entire system is based is one of my inventions, and is shown in Fig. 1, being of substantially Z shape, and made of cast concrete, and is called such in the following description and claims. Faces A and B being equal in their several dimensions, parallel, and extending in opposite directions from a cross web or connecting member C, portion A and B being at right angles with respect to O, 0 having a niche D in the bottom por m which forms an open passage between ce s.

By referring to Fig. 2, it will be seen that units 1, 2 and 3 form hollow cells and these three units are bonded together by the 4th unit in the course above, by inverting the same. The cross web of unit 4; coincides with that of unit 2, thus the cross webs of units in a course coincide with those of units in adjacent courses, forming vertical parallel cells E in the wall, said cells having connecting passages through the niches in the cross webs of units in the wall. By referring to Fig. 8, it will be readily seen how the Z tile lends itself to this substantial means of bonding units together to form a continuous hollow wall, and how the niche in the bottom of the web portion gives horizontal air circulation from cell to cell in hollow wall work, as well as, providing admittance for horizontal reinforcements in reinforced concrete work. In practice, on walls that are to be reinforced with these rods G, the mason lays the rods in place before the next course is laid, the niche in the tile permitting the mason to lay his next course without interference from the rods. The vertical rods H shown in Fig. 3 are the vertical reinforcements that I use for columns made of concrete cast in the cells F, and are tied to the horizontal rods G with wire as the wall goes up. The vertical rods are generally in place as the work progresses, and since the Z tile are virtually halves of a whole unit forming a cell, they are readily put in place around this network of rods. The reinforced cells F of Fig. 3, are then filled with concrete forming columns in the wall, cells E remaining hollow; the number of cells reinforced is according to the required lateral stability and also the supporting power of the wall. inforcements, and their position in the wall, depends upon the amount of tension strain in the wall and the location of the strain.

By referring to Fig. 4, I show a plan View of my reinforced hollow wall of triple thickness having three rows of tile in a course, the center course carrying the concrete and steel reinforcements as shown in Fig. 3, the outside courses K and J being The number of horizontal recoldst'orage work.

This 7 construction I I employ where 7 only a saving of material but a perfect between which is a vital feature in successful By referring to Fig. 5, a modified section of this triple thickness wall is shown in combination with a reinforced concrete floor L, where the vertical reinforcements H extend laterally into the means of eliminating open joints cells,

reinforcements H and floor By referring to Fig. 6, another view of the combination of wall and floor work is shown; here the vertical column rods H laterally into the floor, and I have utilized the Z-tile to produce a hollow light The tile are laid in parallel to form channels between them, in which concrete beams N are cast. The width of the beams varies with the required strength of the floor. The extend laterally from their vertical cells in the wall into these channels, the reinforcements M which are the'tension rods of the said ribs are also placed in these channels. Thus the column beams are cast integral as in cone crete skeleton structural work, but without the use of forms. I employ a metal fabric R for the'bottom slab of this floor constructi'o'nthus providing means for plastering rows, and so spaced as the *ceiling and closing the bottom of the I Fig. 8. A woodenfloor cells P. The niche D provides air communication between 'cells, which is necessary for the-deadening of the sound waves in the floor. If the fioorrstructure is to have a concrete slab top I use a metal fabric S between the slab and the, floor structure, it serving as reinforcement as well as means for bridging the cells P, as is shown by I I 'can be placed on thetop slab, or it can be laid directly on the floor structure as is shown in Fig. 9.

Referring again to Fig. 6, it will be seen that a light metal plaster lath T is laid on the wall between courses 3 and l, and covering the top of the vertical cells in the wall which are to remain hollow, and also to form a base for the cells to be cast solid above it in course 4L. Thus the rod G in course 4c becomes embedded in the concrete forming a reinforced concrete beam. Likewise course 2, 3 and i could be'cast as one beam to carry the floor load over an openingbelo-w by placingthe metal fabric between courses 1 and 2. H Thereby the horizontal rod G in course 2 would act in tension to carrythe load as a beam. This method of reinforcing certain courses 1s also very convenient in carrying the wall over doors and windows.

Fig. 7 shows how I place the vertical reinforcing rods II in a wall supporting a continuous floor.
